DEPOSIT STRUCTURE CHARACTER CaCO3 ON THE SHELLS OF SCALLOP (AMUSIUM PLEURONECTES) AS BIO-INDICATORS OF ENVIRONMENTAL CONDITIONS IN THE BATANG WATERS
ABSTRACT: The objectives are
:(1) Measurement of the character structure of CaCO3 deposit on
simping’sshells, (2) Identifying Environmental Conditions of simping in Batang.
The study will be conducted exploratory descriptive method
(non-experimental). The results showed
as morphometric’s measurement, there’s no difference in the population growth
of simping in Batang from 2003 to current. Based of analysis of the hue-saturation
value which is the phenotype of CaCO3 biomineralization mechanism that is
deposited in the shell, showed that the biological potency (early-stage) of the
character of the population’s simping growth in Batang is better than the
Brebes’s population as a comparison. Conditions of natural habitat in Brebes
relatively better, so that CaCO3 deposits is better also.Based on those
results, efforts to provide science and technology inputs to support the
preservation of aquaculture activities is to engineer a better environment to
support the genetic potential to convert to a more optimum growth rate. Another thing that can do is to optimize the
genetic potential of Batang’s simping as selective-breeding material in marine
culture. It is expected that these strategies can be used to overcome the
problem of limited production scallop in northern coast of Central Java in
order to meet the needs of the market potential through mariculture activities.
